Filed: 1990-11-16
Abstract: PURPOSE:To improve a power factor and to increase an input voltage by a simple circuit by controlling the ON/OFF of a switch in a period shorter than that of the alternating current voltage of an alternating current power supply terminal and controlling an energy storage control circuit so that the current of a reactor can selectively flow through the energy storage control circuit and the switch. CONSTITUTION:The output voltage of an inverter circuit 10 is converted to be direct by a rectifying and smoothing circuit 20, and control for fixing the voltages of output terminals 21 and 22 can be executed by controlling the duty ratio of PWM waves at a first control circuit 15. Namely, an output voltage V0 is adjusted by controlling the ON time width of switches Q1 and Q2. On the other hand, a second control circuit 27 executes control for approximating the current to flow to alternating current power supply terminals 1 and 2 to a sine wave, making the power factor close to '1' and fixing the charging voltage of capacitor C1. Thus, the input voltage of the inverter can be increased and the power factor can be easily improved.

IPC: G02F1/133
Filed: 1994-12-14
Abstract: PURPOSE: To prevent a leakage current and to reduce power consumption by cutting off a path from a ground to the output of a driving circuit by insulating the driving circuit from a current detecting means. CONSTITUTION: The detection of a current flowing through a cold cathode fluorescent lamp 6 is performed through a photocoupler 8, the secondary side of a transformer 5 is connected to neither the + side input terminal 1 of a DC power source nor an input terminal 2 on the ground (GND) side and made to be floating state. Thus, although a detecting circuit 7 for detecting a current flowing through the cold cathode fluorescent lamp 6 is used, a current path through the secondary side of the transformer 5 is cut off through a stray capacity, a mutual conductance due to the components of a liquid crystal display device, as the path of a leakage current. Consequently, power consumption due to a leakage current is reduced.

Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To enhance operativeness by detecting inclination quantity of a control lever for making the first and the second operations in the X, Y axial directions on a plane, making outputs in such a manner as being capable of carrying out both operations simultaneously, and calculating operational speeds respectively in response to those outputs. SOLUTION: The longitudinal inclination and the lateral inclination of a control lever 26 are defined as contractive operation of boom and turning operation thereof respectively. When the control lever 26 is forced to incline in the intermediate direction between directions of Y shaft and X shaft, output is generated to both X shaft, Y shaft potentiometers 23, 33 to be inputted in a controller 41, and the operational speed responding thereto is outputted to an actuator 28 as an hydraulic pressure information. The relationship between an output value of potentiometer and an oil pressure value is recorded in ROM 42. When the relationship between the output value and the oil pressure value is set in linear relationship, the boom contraction speed decreases linearly and a boom turning speed increases linearly as the control lever 26 is moved from Y shaft direction toward X direction.  Accordingly improvement in operativeness can be attempted.

Abstract: PURPOSE: To carry out high frequency lighting of a discharge lamp by installing an inductive apparatus and a capacitive apparatus in respective branches which divide a secondary winding of a voltage transformer and providing a resonance frequency different from a resonance frequency of the load branch. CONSTITUTION: When input terminals 1, 2 are connected to an anode and a cathode, respectively, of a DC electric voltage source, switching elements S1 , S2 are turned on and off at high frequency (f) by a connection circuit 1. As a result, high frequency electric current at the high frequency f flows through a load branch. The high frequency electric current at the high frequency f also flows in two branches which divide a secondary windings Sec1 , Sec2 of a voltage transformer L3 . Since the size of the load branch is determined so as to make the frequency f higher than the resonance frequency of the load branch, the load branch has inductive impedance at the frequency f. Moreover, the size of the branches which divide secondary windings Sec1 , Sec2 of the voltage transformer L3 is determined so as to make the resonance frequency of the branches higher than the frequency f. The impedance of these branches is capacitive.
